UK postcode districts

2,414 postcode districts across England and Wales, holding 1,586,404 live postcodes. Each district page shows the towns inside it, its wards and Westminster constituencies, and its deprivation profile.

A postcode district is the first half of a postcode: BA2, LN12, M1. It is Royal Mail's delivery geography rather than an official statistical one, which is exactly why it is useful: it is the geography people actually know their address by.

Look up any postcode

Ward, council, constituency and the neighbourhood's deprivation decile for any of the 1.75 million live postcodes in England, Wales and Scotland, answered from this site's own copy of the official directories — the lookup fetches one small data file and nothing you type is sent or stored anywhere. Northern Ireland's BT postcodes sit under a separate Land & Property Services licence and are not included.
